Title: Image processing method
Inventor: Iddagoda Hewage Don Mavidu Nipunath Iddagoda
IPC: G06T7/00
Filed: 2015-03-27
Abstract: An image processing method comprises acquiring 102 an image, calculating 108 a combined colour index for each pixel in said image based on the colours contributing to each pixel, and calculating the gradient of said combined colour index for each pixel to obtain colour gradient change data for the total image. Said gradient change data is smoothed 110 to highlight relevant colour changes on said image and sectored 111 to allow information to be extracted from each said sector of the image. At least one anchor point is identified 112 within at least one of the sectors. The anchor point may be used in determining at least one edge in the image. The image may be sectored by grouping similar gradient data together. The combined colour index may be calculated as: Combined Index = Z2 x Red + Z x Green + Blue, where Red, Green and Blue represent the magnitudes of those colours and Z represents the total range of values available for each colour.

Title: Method for estimating a temperature of a transistor
Inventor: BRIJ N SINGH
IPC: H02M1/00
Filed: 2016-02-11
Abstract: A method for estimating junction or die temperature of a transistor comprises measuring turn-off voltage change with respect to change in time between a collector and emitter of a transistor in a phase of and inverter and peak voltage of the transistor between the collector and the emitter. Intermediate parameters of turn-off current, the turn- on current and on-state voltage drop based on the turn-off voltage change and the peak voltage are determined. The power or energy loss for one switching cycle of the transistor based on the turn-off current, the turn-on current and on-state voltage drop between the collector and emitter of the transistor is determined. The associated average die temperature for the transistor over the switching over the switching cycle is estimated based on the determined energy loss, observed inverter system temperature, such as coolant temperature of a coolant in a coolant system for cooling the inverter, and thermal characteristics of an inverter system, such as thermal resistance of a liquid cooled system.

Title: Ion mobility separator for mass spectrometers
Inventor: MELVIN ANDREW PARK
IPC: H01J49/00
Filed: 2012-04-24
Abstract: The invention relates to the selection and separation of ions with predetermined ion mobilities, preferably for mass spectrometric analysis. The invention provides devices and methods for these separations, either by the collection and temporal storage of many ions with predetermined mobility, or by filtering the ions according to their mobility, thus producing a constant beam of ions with predetermined ion mobilities. The invention is based on at least two consecutive ion mobility high pass and/or low pass filters, formed each by the action of a moving gas with its friction force and a counter-directed DC electric field on the ions. An ion mobility high pass filter can be formed by a DC electric force field driving in the ions from an ion source against a flow of gas, whereas an ion mobility low pass filter may be formed by a flow of gas driving entrained ions from an ion source against a DC electric field barrier.

Title: Performing average pooling in hardware
Inventor: WILLIAM JOHN GULLAND
IPC: G06N3/063
Filed: 2017-09-20
Abstract: Convolutional neural network processing system 100 comprises: special-purpose hardware circuit 110 including matrix and vector units 120, 140; and neural network implementation engine 150. When the engine receives requests comprising an average pooling layer, it generates instructions for: a convolution of an input tensor with a kernel the size of the average pooling layer window to generate a first tensor, wherein each element of the kernel is an identity matrix; and dividing each element of the first tensor by the number of window elements to generate an initial output tensor. The kernel can be a two-dimensional matrix of ones. The first convolution generates a sum of the elements of the input sensor within the window. The division is implemented through a masking tensor to obtain an average from the sum. Matrix unit 120 is a systolic array. This allows performing average pooling on an incompatible special-purpose circuit avoiding off-chip computations.
Patent GB-2558708-A (GB)
Title: Method and apparatus
Inventor: Mohammad Reza Bahmanyar
IPC: G01L9/00
Filed: 2017-09-21
Abstract: Implantable pressure sensor device 100 comprises first pressure-dependent transducer 102a and second, reference transducer 102b, which each respond at different alternating e.g. RF electrical signals, separated for example by 1-2MHz. Antenna coupling 104a, 104b may be arranged in parallel with the transducers. Support on deflectable membrane 101 may render one transducer more pressure responsive than the other, for instance because one transducer lies over a cavity 112 containing gas at reference pressure. The different amounts of deflection may also arise due to different substrate thicknesses, which may e.g. be less than 200μm or more than 5µm. Interdigitated transducers (IDTs) may be used, having interlocking comb-shaped conductive fingers on a surface of piezoelectric substrate, possibly arranged to provide surface acoustic wave (SAW) devices, in which the frequency response is determined by the fingers spatial arrangement. Bulk acoustic wave (BAW) resonators may be used. Details of such an IDT are also disclosed.
